On Linux you just use qrencode but you're on Windows.

I don't use filepro on Windows, but, a minute or two of googling yielded 
a command line reader and a command line writer, both free, open source, 
with pre built windows binaries and even windows installers. All I did 
was google "windows command line qrcode".
